Hi Grant,

 thank you very much for your. 

  I have several encfs-encrypted partions. As fas as I had understood
  encfs, only the contents of the data file and not their
  organisational data are encrypted (?).
  But I may be wrong...

  So, do I any harm to shake those partions without mounting them in
  beforehand?

  How can I make a mount -o remount,user_xattr work?
  Do I have to re-mkfs the partions (please not..) ?

  Thank your very much in advance for your help!

  Kind regards,
  Meino Cramer
